Abstract: 834,745. Boring earth. PHILLIPS PETROLEUM CO. April 29,1958 [May 10, 1957], No. 13545/58. Class 85 Well drilling apparatus comprises an upper rotatable seal 26 in sealed engagement with a kelly 20, a lower non-rotatable seal 38 having a lower section 42 connected with the casing head structure 10,... 14 and an upper section 41 in laterally movable sealed contact with the section 42, and a sleeve 34 extending between the seals. The seal 26 which comprises sealing members 29 is connected with the skirt 17 of the kelly bush 18, and the sleeve depends from the seal 26 into sealing members 36, 37 of the seal 38. The members 36, 37 are mounted on the section 41 which has a flange 71 urged by springs 52 into sliding contact with a flange 72 of the section 42. Mounted on the section 42 beneath the sleeve are annular stripper seal members 66, 67 from the inner-edges of which radiate slits so that these members may have sealing engagement with the drill pipe. The upper seal may be arranged on the upper surface of the kelly bush, or upper seals may be arranged on the upper and lower surfaces of the bush. The apparatus is used when the drilling fluid is aerated to prevent lost circulation, to increase the drilling rate, or to allow small amounts of the formation oil or gas entering the fluid.

Abstract: 1,020,461. Mechanical calculating devices. ORTOPEDIA G.m.b.H. April 2, 1964 [Aug. 7, 1963], No. 13594/64. Heading G4B. [Also in Division G1] Two graduated rules 1 and two links 2 are pivoted together with rivets 3 to form a parallelogram and at least one link 2 is extended to form a pointer 4 which moves over a scale 5 on an extension of one of the rules 1 to indicate the distance " h " between the rules 1. The apparatus is transparent and may be placed on an X-ray photograph of a bone to lie along its length with the diametric dimension to be measured located between the inner edges of the rules. Due to the enlargement of, say, 10% in the photograph it is convenient to calibrate one scale 1 and 5 in cms. and mms. respectively, as measured on the photograph and another scale 1 and 5<SP>1</SP> to indicate the dimension of the bone. The apparatus may be used to determine the spike or nail size for bone marrow spiking. When used for plotting or reading constructional drawings it may be convenient to calibrate on scale 5 in degrees for measuring one of the angles α or #.

Abstract: 474,985. Laminated springs. WOODHEAD & SONS, Ltd., J., and SANDERS, T. H. May 15, 1936, No. 13754. [Class 108 (iii)] In a laminated spring having a rolled eye at one or each end of the main spring plate, the eye is made non-circular and formed so as to provide a square or extended heel. As shown, the end of the plate a before being finished to form the actual eye c, is bent at an acute angle, Fig. 1, or more or less sharply, Fig. 2, or at a right-angle, Fig. 4. In each case an extended or square heel d is produced at the back of the eye c and supported by the suitably extended second plate e of the spring. The portion of the plate a below the eye may be straight or curved, as shown in Fig. 1, to provide a seating f for a bush b which receives the anchor bolt or shackle pin. Instead of passing under the bush b, as in the constructions described above, the plate a may first be bent over the top of the bush b and then bent backwards beneath the bush to provide a flat or curved seating for the bush.

The formed fabric element is then removed from the dies and the part formed by the ram 202 and the recess 224 is trimmed-off along the the line 100, Fig. 2, to leave the layer 12, Fig. 1. Before or after trimming the fabric elements along the line 100 it is coated with a rubber layer 14. During deformation of the fabric blank the warp and weft threads 126 and 128 take up the relative positions shown diagrammatically in Fig. 2 so that they provide circumferential extensibility which increases progressively from the top flange 120 to the bottom flange 116. The fabric may be of glass, nylon or either of the materials sold under the Registered Trade Mark "Orlon" " and " Dacron ". Specification 855,348 is referred to.

Abstract: <PICT:1044532/C6-C7/1> Metal objects are tested for inhomogenieties cracks, flows, stresses by applying an electrode to the metal surface with an intervening body of electrolyte, and measuring the variations in voltage which determine variations in successive areas of the "energy state" of the surface.  Either the electrode or the surface or both may move in the test.  The contact with each location is short to avoid polarization effects.  A cylindrical body 73 to be tested is mounted on a rotatable base 71 opposite a stylus 74 filled with electrolyte and carried on a tapped ring 77 which moves upwards by rotating the screw thread 78 on which the ring is mounted.  A voltmeter is connected across terminals 72, 76 which registers voltage as the wet stylus touching the surface 73 scans the area during rotation.  A similar stylus may scan the inner surface of the cylinder.
